PUMP-GOVERNOR.

SPECEFICATIN forming part of Letters Patent No. 409,500, dated August 20, 1889.

Application tiled March 14, 1889. Serial No. 303,231. (No model.)

To all whom may concern,.-

Iie it known that I, JOHN T. PINE, ot' the city, county, and State of New York, have invented an Improvement in Pump-Governors; and the following is declared to be a tnll, clear, and exact description of the saine.

My invention applies to the water-supply for hydraulic elevators for buildings and to the general water-supply systems of buildings in which cases, tanks, or receptacles for holding water are located in the upper stories of the buildings or upon the roof; and Imy invention relates particularly to devices for automatically governing the steam-pump located in the basement by the height of water in the tank at the top of the building, so that when the water in the tank gets low the pump will be started to till up said tank, and when the water has reached a suiiieient height the pump will be automatically stopped. The water to supply this tank on the root will in a hydraulic-elevator system be taken trom a tank or receptacle in the basement, into which the water runs from the stand-pipes with the descent ot the elevator, and in a water-supply system the water to supply this tank will be taken from a well or from the water-supply of the place or city in which the building` is located.

In the drawings, Figure l is an elevation and partial section of the devices employed by me. Fig. 2 is a vertical section, in larger size, of the steam-valve.

A represents a stand -pipe passing up through a building from the basement to the top story or roof, and connected to a tank or water-receptacle A', located at the top of the building, and A2 denotes the floors of the building. This stand-pipe A may form part of the operating mechanism for hydraulic passenger or other elevator, or it may be connected by branch pipes c at each Hoer to the basins, closets, the., in the building for supplying water thereto. 'lhisstand-pipe A is connected with the bottom part ot the reservoir, and may pass up through the bottom or into the side of the tank, as indicated by dotted lines. l

The steam-pump is composed ol the watercylinder B, water-chamber B', steam-cylinder C, plunger D, steam-chest Il, discharge-pi pe E for the water under pressure, and inlet or suction pipe F,and as these parts are well known they do not require further description. The pipe E extends up through the building, and its upper end bends over the upper edge of the tank to deliver into the tank or reservoir A the water forced up by the steampump- The pipe F is connected to any desirable source of water-supply. This in an elevator system would be a receptacle or tank for the water coming from the piston-cylinders with the descent ot the passengercar, and this in an ordinary waterservicc system would be a well or cit-y watersupply.

A branch pipe L is connected to the lower end of the stand-pipe A and rises to the cylinder M, in which is a piston N, having' a cupleather fitting the cylinder. The stem d passes up through the cap of the cylinder and its stufiing-box. Upon the stem (l is a collar d', and surrounding the stem and resting upon the collar d are a number of weights if. Connected to the upper end of the stem cl are chains or cords 7.; It', which pass over pulleys or rollersl Z. vWater iills the branch pipe L and cylinder M from the stand-pipe A, and the weightsz' on the stem d are to be sutiieient to counterbalance the weightof the water in the stand-pipe A, and there is a branch pipe 0 connected to the pipe L and a pressuregage r connected to the pipe o, and this gage r indicates the pressure from the column of water in the stand-pipe and reservoir.

Connected to the steam-chest Il of the steam-pump is a valve-chamber I and steampipe'G. This valve-chamber I contains the balanced companion valves a a', mounted upon the stem l), which stem is guided in the upper and lower portions of the valve-case, and there are seats c c for the valves a a. The upper part of the valve-case that receives the upper end of the stem l) is hollow, and there is a. rock-shaft g, having a bearing h within this case, and there is a lever-arm f connected to the rock-shaft g, and this leverarm f is connected to the upper end of the Valvestem l), and upon the rock-shaft g outside of the case is a lever fm, upon which is a Weight n, and one end of the chain 7o is connected to the end of this lever m. Steam from the pipe G passes through the valve I into the chest H when the valves a a are open.

Below the steam-cylinder C there are drippipes s, the lower ends of which are connected to a longitudinal drip-pipe t, in which is a valve u and Weighted lever fr, and one end of IOO the chain k is connected to lever o.

The operation of the mechanism is as follows: When the water in the tank A has been drawn out for use, so that the tank needs refilling, the weight of the water in the standpipe A will have decreased, so as to allow of the descent of the weighted piston N in the cylinder M. This will draw upon the chain 7c and raise thev lever m and open the valves in the valve-chamber I, and admit steam from the pipe Gto operate the steam-pump, so that water is forced into the tank A by the pipe E. As the tank fills with water the pressure due to the column of water in the stand-pipe increases and the weighted piston N is gradually raised and the lever m gradually falls, and when the water in the tank reaches a height at which its pressure is balanced by the weights z', previously regulated, the lever m will have descended fully and the valves a a be closed to their seats and the supply of steam shut oft'. These operations are continuously repeated with every fall of water in the tank, thus providing for the automatic regulating ofthe steam-p u 1n p.

The drip-pipes s and t are designed to receive from the steam-cylinder C any water that may collect therein, and said water is discharged into these drip-pipes through the small cocks s and passes into the pipes s and t. This water accumulates, and the same is periodically drained by the opening of the valve u by the lever t and chain 7c with every up-and-down movement of the weighted piston N.

My improved device as herein described is especially adapted for use in large office buildings or apartment houses or large stores where there are either hydraulic elevators or water-supply systems with tanks or water-receptacles in the upper story or upon the roof, and my improvements are very useful, inexpensive, and effective for automatically governing the operations of the steam-pump so that the tank may be replenished whenever necessary.

If desired, the branch pipe L, instead of being connected to the supply stand-pipe A, might be connected to an independent standpipe of smaller dimensions from the same tank or receptacle, in which the pressure due to the height of water would operate as effectively as in the supply stand-pipe.

I claim as my inventionl. The combination, with an elevated waterreceptacle in the upper part of a building and a steam-pump and pipe therefrom to the tank, 0f a vertical supply stand-pipe connected with the tank and passing down through the building, a branch pipe connected to the standpipe, and a vertical cylinder upon the branch pipe, a piston and rod moving within said cylinder, and variable weights upon the rod to counterpoise the weight of water in the standpipe and tank to the desired level, and pulleys and aconnection from the weighted piston to the end of this the valve of the steam-pump, whereby the weighted piston is raised and the valve is moved by the increase of pressure due to the rise of the water in the tankl and the reverse, substantially as specified.

2. The combination, with an elevated waterreceptacle in the upper part of a building and a steam-pump and pipe therefrom to the tank, of a vertical supply stand-pipe connected with the tank and passing down through the building, a branch pipe connected to the standpipe, and a vertical cylinder upon the branch pipe, a piston and rod moving Within said cylinder, and variable weights upon the rod to counterpoise the weight of water in the standpipe and tank to the desired level, and the steam-valve chamber I and valve, and the weighted lever 'm connected therewith, and pulleys, and a chain over the pulleys connecting the weighted piston and weighted lever,

whereby the weighted piston is raised and the valve is moved by the increase of pressure, due to the rise of the water in the tank and the reverse, substantially as specified.

3. The combination, with a water tank or receptacle in the upper part of a building, a vertical stand-pipe connected therewith and passing down through the building, and a steam-p u mp and pipe therefrom to the tank, of a branch pipe connected to t-he stand-pipe and a cylinder upon the branch pipe, a weighted piston within said cylinder, the steam-valve chamber I and valve, and the weighted lever m connected therewith, and a chain 7e, and pulleys around which said chain passes, the ends of the chain being connected, respectively, to the weighted piston N and weighted lever m, and a branch pipe o, connected to the pipe L, and a pressure-gage r to indicate the pressure of the weight of water in the stand-pipe and the variations thereof, substantially as set forth.

4. The combination, with a water tank or receptacle in the upper part of a building, a vertical stand-pipe connected therewith and passing down through the building, and a steam-pump and pipe therefrom to the tank, of a branch pipe connected to the stand-pipe and a cylinder upon the branch pipe, a weighted piston within said cylinder, the steam-valve chamber I and valves, and the weighted lever m connected therewith, and a chain 7e, and pulleys around which said chain passes, the ends of the chain being connected, respectively, to the weighted piston N and weighted lever m, the drip-pipes 8 and t, connected to the steam-cylinder of the pump, and a valve u, lever t, chain 7o', and pulleys t" for the same, one end of the chain 7c being connected to the weighted lever Q: and the other end to the weighted piston N, substantially as and forthe purposes set forth.
